Manufacture of high temperature insulating textiles
Apronor >
Apronor offers a range of industrial, insulating and heat-resistant woven textiles with various treatments, in particular vermiculite and graphite impregnations, silicone, polyurethane or even PVC coatings and with aluminum lamination.
Insulation helps limit heat transfer and therefore reduce the amount of energy required to raise temperatures and protect adjacent materials from heat damage. Since the dangers of using asbestos were identified, several alternatives have been developed in situations where high temperatures are present. However, all technical textiles have one thing in common: providing textile solutions to the needs expressed by their users. Either they make it possible to produce finished products that could not be designed with other materials, or they provide a better solution than other materials from a technical or economic point of view.
Technical fabrics
Technical textiles are characterized by their specific technical skills and are intended for well-defined applications (insulation, waterproofing, impermeability, cut protection, electrical conductivity, etc.).
They provide a solution where flexibility of movement is needed, in situations where temperatures are extreme. Heat resistant materials capable of being made into fibers can be woven, braided, knitted or needled as needed.
Aramid fabrics
Aramid fabrics, which are also known under the trade name KevlarĀ® or NomexĀ®, are heat resistant up to +/- 250 Ā° C. They allow thermal and sound insulation of materials used in several fields and their use is very widespread in ballistic applications.
Aramid fabric is made of fibers that retain excellent mechanical properties at high temperatures. They can replace glass fibers and metal and find their applications in tires, ropes, bulletproof vests and special materials intended for industry.
- Low thermal expansion
- High tensile strength
- Good chemical and abrasion resistance
- Great solidity
- Aeronautics/Aerospace
- Shipbuilding/Military/Ballistics
- Automotive (Belts, etc.)
- Sport/Ski slope/Water sports
These aramid fabrics have a polyurethane coating applied to their surface in order to modify their technical characteristics and appearance. The coating gives them the following characteristics: stain resistance, impermeability, abrasion resistance, antistatic, etc.
The aluminized aramid fabrics are intended for the manufacture of protective clothing and thermal insulation for example.
Carbon fabrics
Carbon fiber is a fabric made from a polymer that undergoes high temperature treatment, oxidation and carbonization. Composed of composite fibers and carbon atoms, carbon fabric is used to reinforce composite materials for applications requiring high mechanical strength at low weight. These fabrics use fibers produced under strictly controlled conditions and are subjected to numerous tests in accordance with a strict quality charter.

Glass fabrics
Glass fabrics are made from a fiberglass that withstands temperatures up to 800Ā°C. Likewise, it is incombustible and thanks to its chemical resistance, it is ideal for specific industrial applications.
- Incombustible
- Temperature resistance
- Insulating
- Natural material

The caramelized glass fabric undergoes a desizing treatment which caramelizes the fiber. This treatment increases the temperature resistance performance and limits the release of smoke during the first temperature rise.
Polyurethane is an organic polymer used in textile coating processes. It provides airtightness and good resistance to fraying. The polyurethane can be dyed in the mass according to a standard or specific color. For grinding or welding protection applications, the polyurethane coating slows down the penetration of the textile by incandescent scrapes.
The anti-fraying treatment process involves impregnating the fiber with an acrylic-based formulation to fix it.
Polyvinyl chloride, commonly called PVC, is a fusible material used in particular in coating processes on textiles. This coating provides water and dust tightness. The PVC coated fabric can be assembled by welding, providing waterproofing and rapid assembly.
The unbleached glass fabric has not undergone any transformation or preparation.
Vermiculite is a natural mineral which has excellent insulation and fire resistance properties. The vermiculite coating provides resistance to high temperatures of up to 1000 Ā° C over a short period of time. Glass fabrics with a vermiculite coating are used in particular in the fields of welding protection or to protect incandescent projections (metallurgical industry, foundry, etc.)
Polytetrafluoroethylene (PTFE sign) – commonly called TEFLONĀ® after the name of the trademark registered by the American company Dupont de Nemours – is a semi-crystalline, thermostable fluoropolymer (-200 Ā° C – + 260 Ā° C). The TEFLONĀ® coating gives the textile a strong sliding power and improves resistance to chemical agents.
